How many words do Xiao Li and Xiao Ming type each minute? Xiao Li and her father practice walking race. Dad walks 50 meters more than Xiao Li every minute. When Dad walks 1800 meters, Xiao Li just walks 1200 meters. How many meters does Xiao Li walk every minute?

Xiaoming 50, Xiaoli 60
Let Xiaoming score x per point, and Xiaoli score 1.2x
300/1.2X +1=300/X
Find x = 50
Let Xiao Li walk x meters per minute
1800/X+50=1200/X
X = 100m

Dad and Xiao Li practice walking on the pedestrian walk. Dad walks 200 meters more than Xiao Li. It's known that Dad's speed is faster than Xiao Li's. thank you,
Dad and Xiao Li practice walking on the pedestrian walk. Dad walked 200 meters more than Xiao Li. It is known that Dad's speed is 40 meters / minute faster than Xiao Li's. The walking time of the two people is 3 minutes and 2 minutes respectively. So how many meters did these two people walk?

Let Xiao Li's velocity be x and dad's velocity be: (x + 40) 3 × (x + 40) - 2x = 200. The solution is: x = 80, dad is 120, 80 × 2 = 160, 120 × 3 = 360

It costs 17.5 yuan to take Xiao Li to the amusement park. It is known that the price of an adult ticket is equal to that of two children tickets. How much is an adult ticket?
